ELEVATOR.

Be it known that I, SAMUEL JAMEs Terri; a citizen ofvthe United-States, residing at Carlisle, in the county of Cumberland and State of Pennsylvania, have invented certain new and useful Improvements in Elevators, ofwhichthe-followingis a specification. Y

This inventioncrelatesto elevators and more particularlyto elevators designed for the purpose of carrying corn stalks, fodder,

. ferent parts of the bin or silo.

or the like materials up into a bin, silo, or other suitablereceptacle. f H The general object of this invention is to provide a verysimple and readily adjusted. elevator of this character. which .may be readily engaged with or disengaged from the bin or like structure in which the mate.- rial is tobe discharged and which-may be adjusted todischarge the material into dif- A further objectis to provide an elevator. of this character so constructed that the carriers will occupy theleast possible space when descending after discharging the material therefrom so that the elevato'r may be compact in form and disposed close to asilo, bin, or other structure. Other objects will appear in the course of the following description. c v Myinvention is illustrated in tllflfl-CCOIH- panyingdrawings, wherein Figure l isa fragmentary view inside elevation illustrating an elevator constructed in. accordance -with an embodiment of my invention.

Figure Q is a View in; front elevation of thestructure illustratedin Figure 1. with certain of the parts shown Figure 1 omitted.

v .Figure "3 is an enlarged horizontal sectional view taken through the lowerportion of the structure as illustrated in Figures and2. v

Figure 4 is a fragmentary vertical sectional view taken throughthe structure as illustrated in Figure 8,- and V Figure 5 is a fragmentary view in top I plan. illustrating the means for maintaining the device indesired lateral adjustment.

. I Figure 6 is a fragmentary elevation of the hangers 9 and the supporting wheels 11 and allied parts, the sprocket chainsl2 being in section. 5

As disclosed in the accompanying drawings, myimproved elevator includes two ja cent side member 1. By lengthening or Specification of Letters Patent. Patented g Application filed September 1919- Serial No. 32 358. I I

substantially parallelside members 1 which, when in working position, are substantially vertically disposed. The lower ends ofthe members l rotatably'support a transversely disposedv shaft 2 extending outwardl y bewheels 3- has disposedtherearound a chain at in driven connection with a driveshaft 5 rotated 'in' any desired manner, preferably through the instrumentality of a motor The upper end portions of the side members 1 rotatably support a second trans. verse shaft'o, and ,pivotally engaged withv said shaft 6- adjacent to members' 1 are the horizontally disposed members 7 of desired length. Each of the. members 7 is held against swingingv movement by a brace connecting said. member 17 and the adshortening the brace member f7: each of the side members] may be readily and; con ven ently ad usted with respect to the coactin 'v side member 1, and as the occasions of practice may require. Theouter'or' free end portions of the member 7 rotatably sup I port a third transversely disposed shaft 8, and the inner end portions of, said member 7 havefdep ending therefromfthe substantially transversely aligned'arins or brackets 9, which rotatably" support transversely extending, inwardly projecting stub shafts 10 (see Flgure 6) which support the sprocket wheels 11?.

The shafts 2, 6, and -8 have afiixed thereto adjacent their opposite ends but inwardly of the membersl, the sprocket wheels 11, with which .coact the endless chains'12,'the

direction of rotationof the shaft 5 being r.

such as to cause the outer stretches' of said chains to travel upwardly. Y

Mounted upon the chains 12in predetermined spaced relation are the'carriers B.

Each carrier has substantially triangular end members. Each of these end members includes an upper, outwardly projecting i bar 14; and .a-lower, upwardly projecting supporting bar le 'on each side of the carrier, the twobar's 14} and ll forming each end of the carrier converging attheir outer ends and being rigidly "connected to each brace 17. The upper bars 14 offthe endmembers of the bucket are pivoted to a transverse rod 15 which engages the two parallel other. E'achipair of bars is engagedbya I chains 12, while the lower bars 14 are connected by means of a transverse rod 16 which, on the upward flight of the carrier, bears against that portion of the chain .be low the transverse pivot member 15. The lower bars 14 are connected by means of a transverse brace bar 19. It will be seen that each carrier B is pivotally connected to the chains 12 at its upper inner corner by means of a transverse rod 15. Extending from the transverse rod 15 are a plurality of tines 18 (see Figure 3) which are disposed in the same plane and in parallel relation to the bars 14.

Upon the upward movement of the chain, as upon the outer flight thereof, the bars 14 are supported in an upwardlyand outwardly inclined position by means of the bars 145 -whose transverse rods 16 bear against the chain, as illustrated most clearly in Figure 1 and in Figure 4;. Thus the tines 18 and the members 14 extend upwardly and outwardly in position to support a load and carry the load upward as the chains move upward. Those links of the chains 12 immediately adjacent the cross rod 15 of each oi? the carriers and disposed above the carriers when the buckets are moving upwardly are pivotally connected by transversely disposed rods 15'. These rods provide a back for the carrier which prevents the load from spilling out as a carrier moves upward or when the carrier moves horizontally after it has reached the upper end of the elevator.

' The carriers are supported in an upwardly and outwardly projected position as they move upward and as they move horizontally along the upper flight of the endless chains and after a carrier passes the wheels 11 on the outer ends of thearms 7 the carriers are still held in an outwardly projecting position but extending inward toward the clownwardly moving flight of the chain. After the chains have passed the wheels 11 however, the carriers take the position shown in Figure 1 and in Figure 1, that is they hang straight downward or as nearly straight downward as it is possible for them to hang and contact withthe chains 12. It will be obvious that as the carriers move upward they will carry up the material to be elevated and carry the material inward to a position above the storage bin, silo or other receptacle, whose breast or sill of the door opening is designated 24:, and that as the carriers pass around the wheels 11 and the outer ends er the arms 7, the material will be discharged into the bin, silo or other receptacle.

F or the purpose of supporting the elevator in proper position on the receptacle and permitting the elevator to be turned in a horizontal plane, the upper end portions of the members 1 have engaged therewith the rearwardly directed beams-20, whose outer ends are connected by a transverse beam 21.

Extending from the transverse beam 21 is a beam or arm 22, which carries a downvv'ardly extending'pin 26 disposed in the socket 25 formed in a plate 23 resting upon the upper face of the sill or breast 2a of.

the storage receptacle. This pin 26 carries an arm 27 and the inner edge of the plate 23 is upwardly flanged and formed with teeth 28 with which the arm 27 is adapted to be engaged. Thus it will'be' seen that the beam 22 and, therefore, the elevator may be oscillated around the pivot pin 26'and thus the elevator may different points of the receptacle.

The beams 1 and 7 are each provided with the side plates 29, between which the-carriers B travel. The adjacent ends of the plates 29 of the beams land 7 are provided with the overlapping corner plates 30, so that said plates 29 of the members 1 and 7 will be substantially in continuity irrespective of the adjustment of the members 7 with respect to the members 1.

H denotes a feeding or delivery hopper for coaction with the elevator, and this hopper has its bottom 31 inclined toward" the delivery or discharge opening 32 arranged in the lower portion of the front Wall 33 of the hopper. The opening 32 is of a width substantially equal to the spacebetween the side plates 29. The bottom 31 of tl1e-hopper H below the opening 32 is provided with the outstanding and substantially horizontally disposed spaced fingers 3a, which extend between the side plates 29 and between which the tines or arms 18 of the car riers B travel upon theupward movement of said carriers. The corn stalks or other ma terial to be elevated, are deposited in the hopper H and pass by gravity out through the opening 32 onto the fingers 34, and as the carriers B pass upwardly, they receive their load from the fingers 34;.

It will be seen that this elevator is relatively light, that it may be easily handled and put in place through the'fillingopening of a silo or over the top of a bin or through an air opening in a barn or other storage place and that when in place it isan easy matter to shift the elevator upon its pivot 26 so as to cause the material to be discharged evenly within the silo, barn" or other receptacle. 7 that because of the fact that the carriers B depend, as shown in Figure 1, approximately parallel to the direction of movement of the flight to which they are attached, that the elevator may be placed very closely adjacent Itis to be particularly noted I the wall of a storage bin orotherreceptacle,
